I am using the Significant motion interrupt. I am using below code:- /* Status of api are returned to this variable. */ int8_t rslt; /* Structure to define the type of sensor and its configurations. */ struct bmi2_sens_config config; /* Accel sensor and significant-motion feature are listed in array. */ uint8_t sens_list[2] = { BMI2_ACCEL, BMI2_SIG_MOTION }; /* Variable to get significant-motion interrupt status. */ uint16_t int_status = 0; /* Sensor initialization configuration. */ struct bmi2_dev bmi2_dev; /* Select features and their pins to be mapped to. */ struct bmi2_sens_int_config sens_int = { .type = BMI2_SIG_MOTION, .hw_int_pin = BMI2_INT_BOTH }; /* Interface reference is given as a parameter * For I2C : BMI2_I2C_INTF * For SPI : BMI2_SPI_INTF */ rslt = bmi2_interface_init(&bmi2_dev, BMI2_I2C_INTF); bmi2_error_codes_print_result(rslt); /* Initialize bmi270. */ rslt = bmi270_init(&bmi2_dev); bmi2_error_codes_print_result(rslt); if (rslt == BMI2_OK) { /* Enable the selected sensors. */ rslt = bmi270_sensor_enable(sens_list, 2, &bmi2_dev); bmi2_error_codes_print_result(rslt); /* Configure the type of feature. */ config.type = BMI2_SIG_MOTION; if (rslt == BMI2_OK) { /* Get default configurations for the type of feature selected. */ rslt = bmi270_get_sensor_config(&config, 1, &bmi2_dev); bmi2_error_codes_print_result(rslt); if (rslt == BMI2_OK) { /* Map the feature interrupt for significant-motion. */ rslt = bmi270_map_feat_int(&sens_int, 1, &bmi2_dev); bmi2_error_codes_print_result(rslt); /* By default the significant-motion interrupt occurs when the sensor is in motion for about 5 seconds. * */ printf("Move the board for 5 secs in any direction\n"); do { /* To get the interrupt status of significant-motion. */ rslt = bmi2_get_int_status(&int_status, &bmi2_dev); bmi2_error_codes_print_result(rslt); /* To check the interrupt status of significant-motion. */ if (int_status & BMI270_SIG_MOT_STATUS_MASK) { printf("Significant motion interrupt is generated\n"); //break; } } while (rslt == BMI2_OK); } } } while(1) { k_msleep(1000); } ...
